Hook n ladder 1 Posted August 13, 2008 Share Posted August 13, 2008 Correct me if I'm wrong....a spring suspension is rated mostly because of the springs. You wanted a higher rating you changed springs or added springs.What about air ride? If I wanted to increase my rear axle rating what would I need to do? Bigger air bags? I want to add about 6000 to 10000 lbs (rating) to my drive tandems.Thanx,Rob Quote Link to comment https://www.bigmacktrucks.com/topic/4105-rear-air-ride/ Share on other sites More sharing options...

For instance the bearings, axle shaft sizes, housing structure etc...You can add a heavier spring pack, or more leaves, or larger capacity air bags in your case but you could possibly be outside of the designers safety factor or window with modifications. I believe the brackets that support the air bags are heavier duty on a 44,000# suspension rating than that of a 38,000# rating, (for example).Rob Quote Plodding along with no job nor practical application for my existence, but still trying to fix what's broke.
